Connecticut Registered Agent.co Review (2026)

Connecticut Registered Agent.co charges $99 a year for Connecticut registered agent service, with the same $99 at renewal. The plan includes an in-state street address for the registered office and online scans of legal papers served on the company. The company also forms a Connecticut LLC for $199 plus the state fee, counting the first year of agent service in that price. It also handles foreign registration in Connecticut at $199 plus the state fee. Score note: a good match for a Connecticut-only company that wants a flat agent price and files its own annual report.

The $99 plan, line by line

For $99 a year, Connecticut Registered Agent.co acts as the Connecticut registered agent. You receive an in-state street address for the registered office, and papers served on the company are scanned and posted to your account. Renewal holds at $99.

Using Connecticut Registered Agent.co to form a Connecticut LLC

Connecticut Registered Agent.co prepares and files the formation document for $199; the state's filing fee is billed separately. Year one of registered agent service comes with it, and the agent runs $99 a year afterwards. The EIN application is a $99 extra, though the IRS charges nothing for an EIN.

Later, Connecticut asks for the annual report every year, due on or before March 31 with a $80 fee. Connecticut Registered Agent.co does not file it, so it stays on your list.

Bringing an existing company into Connecticut with Connecticut Registered Agent.co

Connecticut Registered Agent.co sends the registration to the state for $199, and Connecticut's $120 fee is added. A year of registered agent service rides along. You supply certificate of existence (certificate of good standing) from the state of formation, issued within 90 days.

Where Connecticut Registered Agent.co stands against Mainstay Filing

Agent service alone adds up to $297 over three years at Connecticut Registered Agent.co and $447 at Mainstay Filing, a $150 spread. Mainstay Filing runs a single agent plan across all fifty states and scans the first three government mailings a year free. Mainstay Filing's formation package costs $199 a year and adds the annual report, while Connecticut Registered Agent.co's LLC route totals $397 over three years with the agent but no report filing. CT Registered Agent.org is the other Connecticut agent on the card; it charges the same $99 a year, and the two sit close together.
